Abstrakt: People reactively adjust attentional control based on the history of conflict experiences at different locations resulting in location-specific proportion compatibility (LSPC) effects. Weidler et al. (2022, Journal of Experimental Psychology: Human Perception and Performance, 48[4], 312-330) found that LSPC effects were larger when stimuli were presented on the horizontal axis (i.e., locations to left and right of fixation) compared with the vertical axis (i.e., locations above and below fixation). They proposed and provided initial evidence suggesting left/right locations may represent a special design feature that leads to stronger LSPC effects (i.e., horizontal precedence account). However, their use of horizontally oriented flanker stimuli, which required participants to traverse through the distracting flankers to select the central target selectively in the horizontal axis condition, may have contributed to the horizontal advantage they observed (i.e., gaze path account). The present study tested competing predictions of these two accounts. Experiment 1 used vertically oriented flanker stimuli and compared the findings with Weidler et al. The LSPC effect was larger for vertically oriented stimuli on the vertical axis, and horizontally oriented stimuli on the horizontal axis, supporting the gaze path account. Experiment 2 used flanker stimuli that required participants to traverse through distracting flankers regardless of the axis on which stimuli were presented. The LSPC effect was equivalent between the vertical axis and horizontal axis conditions. These results further supported the gaze path account and suggest that the critical design feature for amplifying LSPC effects is not left/right locations per se, but rather use of stimuli/axis combinations that encourage processing of the distractor dimension.
